Air Velocity Transmitter for HVAC Applications
The EE650 air flow sensor is dedicated for accurate and reliable measurement in building automation and ventilation applications. Whether installed as a duct-mounted unit or employed with a remote probe, it exhibits robust performance and a remarkable resistance to pollutants.
• Measuring range 0.2 – 10/15/20 m/s (40 – 2000/3000/4000 ft/min), user selectable
• Current and voltage outputs, selectable:0-10V,4-20mA
• RS485 interface with Modbus RTU or BACnet MS/TP
• Duct mount and remote probe versions
• Response time: Response time – user selectable typ. 4 sec or typ. 1 sec.
• Power supply: 24V dc
For the EE650 with analogue output, the measuring range 0...10 / 15 / 20 m/s (0...2 000 / 3 000 / 4 000 ft/min), the output signal 4 - 20 mA or 0 - 10 V as well as the response time 1 or 4 seconds are selectable by jumpers.
The response time, the termination resistor and the bus address of the Modbus RTU and BACnet MS/TP versions can also be easily set on the electronics board.
EE650 employs the new VTQ air flow sensor element, which operates on the thermal anemometer principle and is manufactured by E+E in state-of-the-art thin film technology.
The enclosure design and the mounting flange included in the scope of supply allow for easy installation or replacement.
